Language Environment (LE) Requirements

LE is the language environment. The Assembler, C and COBOL for MVS compilers are required for application development under this environment.

You must ensure the CICS region is LE enabled, and that the CICS region startup JCL and procedures include the LE run-time libraries.

Note that IBM TCP uses the OE socket interface. Therefore, all user IDs running EMS client programs must have an OMVS UID and GID. Define these values in the OMVS segment of the USERID and GROUP records in RACF.
